Sodium Naphthalene Sulphonate based raw material designed for high water reducing in concrete admixture formulations as raw material. Product “sodium naphthalene Sulphonate” is a dispersing agent. Since Sodium Naphthalene Sulphonate contains a sodium ion bound to a large organic molecule, Sodium Naphthalene Sulphonate has surface active property and its structure enables the homogeneous dispersion of organic and inorganic dispersions. This chemical product can be presented under two different trade names : “Sodium naphthalene ZWL-I” and “Powercon-100. Both are presented in the form of brown powders with the same chemical properties although they are used in different sectors. Both are water soluble products. “Sodium naphthalene ZWL-I” is a ready-to-use superplasticizer used in concrete, in industrial and civil buildings and in miscellaneous engineering. Sodium Naphthalene Sulphonate consists of an aromatic Sulphonated polymer (92 %) and the dosage in the concrete might range from 0.3 % to 1.8 %.

The water solubility determination of test item Sodium naphthalene sulphonate; was doneb spectrophotometric method. The water solubility was determine to be 496240 mg/L at 25°C. Based on the data from ACD labs, surface tension for sodium naphthalene-1-Sulphonate was predicted to be 58.7 mN/m. The flash point determination of Sodium naphthalene-1-sulphonate done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was determined to be 227°C at 964.9hPa. sodium naphthalene-1-Sulphonate did not catch fire on being exposed to air at room temperature of 27 °C pressure of 966 hPa. This indicates that sodium naphthalene-1-Sulphonate is not auto-flammable. sodium naphthalene-1-Sulphonate does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with Sodium Naphthalene Sulphonate .

Sodium Naphthalene Sulphonate can be concluded that sodium naphthalene-1-Sulphonate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus sodium naphthalene-1-Sulphonate was considered non-flammable for chemical safety assessment. The pH determination of test item Sodium naphthalene-1-sulphonate was done following OECD guideline 122. pH of 1% w/v solution was measured with the help of pH meter and Sodium Naphthalene Sulphonate was observed to be 6.00 at 25 °C.

Based on these half-life values, Sodium Naphthalene Sulphonate is concluded that the test chemical sodium naphthalene-1-Sulphonate is not hydrolysable. The acute oral toxicity dose (LD50) for sodium naphthalene-1-Sulphonate was based on data available for the structurally similar read across chemicals. The LD50 value is greater than 2000 mg/kg bw.

Sodium naphthalene sulphonate has a particle size distribution to be in the range of 150 micron to 10 micron. The normal conditions of use of this substance will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalatory route will be highly unlikely. Therefore this end point for single dose toxicity by inhalation route is considered for waiver. The acute dermal toxicity dose (LD50) for sodium naphthalene-1-Sulphonate (130-14-3) was based on data available for the structurally similar read across chemicals. The LD50 value is greater than 2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, sodium naphthalene-1-Sulphonate (130-14-3) cannot be classified for acute dermal toxicity. Based on the available data for the structurally similar read across chemicals and applying the weight of evidence approach, Sodium Naphthalene Sulphonate can be concluded that Sodium naphthalene Sulphonatewill also behave in similar manner that of the read across chemicals.

The normal conditions of use of this substance will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalatory route will be highly unlikely. Therefore this end point for repeated dose toxicity by inhalation route is considered for waiver. The acute dermal toxicity value for Sodium naphthalene-1-sulphonate is >2000 mg/kg body weight. Considering this, the end point for repeated dermal toxicity is considered as waiver.

Sodium NaphthaleneSulphonates are derivatives of sulfonic acid which contain a naphthalene functional unit. A related family of compounds are the aminonaphthalenesulfonic acids. Of commercial importance are the alkylnaphthalene Sulphonates, which are used as superplasticizers in concrete. They are produced on a large scale by condensation of naphthaleneSulphonate or alkylnaphthaleneSulphonates with formaldehyde. Technical progress in this sector has been extraordinarily rapid. Recent advances permit the concrete admixture designer to achieve excellent workability and remarkable slump life, whilst minimising set retardation. High workability of concrete, resulting in easy placement without reduction in cement content High strength concrete with normal workability but lower water content. A concrete mix with less cement but normal strength and workability.

Sodium Naphthalene Sulphonate improved product quality, with lower content of free sulphates. Crystallization of sulphate during cold weather periods can thereby be avoided. Improved colour, important especially in the application of products for preparation of latices. Higher activity of the product. Lower raw material consumption, by reduction of sulphuric acid and correspondingly also reduction of the neutralisation agent required. Poly Naphthalene Sulphonates (PNS), the Super-plasticiser "work horse" internationally, Poly Melamine Sulphonates - a specialty product for specialised applications, PolyCarboxylates. In addition to concrete applications, these products find uses in other major industry sectors, for example gypsum plasterboard, dry-mix formulations and mining. Naphthalene Sulphonates can be used in a variety of applications.

Sodium Naphthalene Sulphonates can be utilized in water-based cleaners such as carpet shampoos, automatic dishwashing detergents, and industrial detergents, as well as in emulsion polymerization, photographic solutions, and agricultural formulations. One grade of naphthalene Sulphonate can also be used as a dispersant in many areas, which include textile chemicals, pesticide formulations, cements, emulsion polymerization, pigments and dyestuffs, and leather tanning. Many important characteristics of concrete are influenced by the ratio of water to cementitious materials used in the mixture. By reducing the amount of water, the cement paste will have higher density, which results in higher paste quality. An increase in paste quality will yield higher compressive and flexural strength, lower permeability, increase resistance to weathering, improve the bond of concrete and reinforcement, reduce the volume change from drying and wetting, and reduce shrinkage cracking tendencies.

Sodium Naphthalene Sulphonates, also known as high range water reducers, are chemical admixtures used where well-dispersed particle suspension is required. These polymers are used as dispersants to avoid particle segregation (gravel, coarse and fine sands), and to improve the flow characteristics (rheology) of suspensions such as in concrete applications. A concrete mix with less cement but normal strength and workability. The advent of these materials made Sodium Naphthalene Sulphonate possible for the first time to: economically batch workable concretes with water/cement ratios of 0.3 or less, batch Silica Fume concrete at low water/cement ratios, achieve super-fluid, highly workable concretes without excessive set extension. Their addition to concrete or mortar allows the reduction of the water to cement ratio, not affecting the workability of the mixture, and enables the production of self-consolidating concrete and high performance concrete. This effect drastically improves the performance of the hardening fresh paste.

The strength of concrete increases when the water to cement ratio decreases. However, their working mechanisms lack a full understanding, revealing in certain cases cement-superplasticizer incompatibilities. Another benefit of superplasticizers is concrete early strength enhancement (50 to 75%). The initial setting time may be accelerated up to an hour earlier or retarded to be an hour later according to its chemical reaction. Retardation is sometimes associated with range of cement particle between 4 – 30 mm. The use of superplasticizers does not significantly affect surface tension of water and does not entrain a significant amount of air. The main disadvantage of superplasticizer usage is loss of workability as a result of rapid slump loss and incompatibility of cement and superplasticizers.
